Is it so bad that i want an iphone 6?

I mean.i've just wanted an iphone since the 5 came out. I've been telling my mom repetitive times i wanted it. Now she's all day nagging at me that i don't study but still want an iphone. The other day she suddenly was like "well if my daughter wants it so bad, then i should buy it for her" but again today she hears how expensive it is and is all like "its all your fault, do you even care about your family, all you talk about is the iphone" i just want to own one so badly, its all ican think about. Being my mom, shouldn't she buy me one? My birthday was the other day, but still she won't buy me one! Girls younger than me already have it, why can't i have one? Ughh! I know that its not my mom's obligation to buy me one; but still.
If i had a daughter and there was something so badly she wanted i would buy it for her. And its not like we're poor. My mom could buy it and nothing would happen. What do you think?

Is a 16gb iPhone 6 enough for me? (Here's what I do)?

-Music
I had a Blackberry 5gb prior and only had about 200 songs.
-Games
I don't do much hardcore gaming on my phone, but I was a casual gamer on my Blackberry. The games took very little space though and were usually to numb time.
-Pictures
I took a lot of pictures. So that would be important to me.

Although, is it worth having most of my music on Spotify with the new iPhone so that I don't use a lot of space and music would be pretty much covered. But that feature requires Spotify premium, so I'm not sure if it's worth $10 a month.
